This is not just another jigsaw puzzle. You have to read the mystery booklet and then solve the 1000pc puzzle. Read about suspects who have an unusual 'obsession' with Alfred Hitchcock and his films. Then assemble the puzzle to discover hidden clues and filter out the red herrings to catch a psychopathic killer with an obvious fixation for Hitch's famous flicks. And beware - the puzzle is different from the box cover. Suits ages 15 years and over.
